Window Supplier in Chicago
Professional Window Installation and Replacement You Can Trust
In Chicago, the right window depends on the home. Older bungalows need units that fit non-standard openings. Newer builds need energy-rated glass that holds up against the climate. Everything in between needs a style that works with the architecture — and an installation that lasts. This page covers the window types we supply and install for Chicago homeowners — double-hung, casement, bay, picture, and custom. Browse the styles below to find what fits your home, then contact us for a free on-site estimate. Windows are sourced from trusted manufacturers and installed by the same crew that sold them. One point of contact, start to finish.
Double-Hung Window Installation in Chicago
The double-hung is the most common window in Chicago homes. It is also the one that fails the most — because most of them are decades old and well past their service life. Both sashes on a double-hung slide independently. The top comes down, the bottom goes up. That means you can clean both sides from inside the house without going outside. New units seal tighter than the wood and aluminum versions they replace. They operate on a smooth balance system — no more painted-shut sashes or rattling frames. Chicago bungalows on the Northwest and Southwest sides were built with double-hung windows as standard. Most of those windows are now 60 to 80 years old. Double-hung window replacement in those neighborhoods is the most frequent job we run. The rough openings are standard, the swap is clean, and homeowners notice the difference immediately in comfort and noise reduction.
Casement Window Installation in Chicago
Casement windows open outward on a hinge. That single design feature makes them one of the best-performing window types available for Chicago's climate. When a casement closes, the sash presses against the frame from the outside in — creating a compression seal that is tighter than any sliding window can achieve. That means less air infiltration, better insulation, and a window that performs in January the way it performs in July. Crank-out window installation is also simpler than it looks — most jobs require no changes to the rough opening. Newer construction in Lincoln Square and Albany Park frequently uses casement windows on side-facing openings where a double-hung won't catch cross-ventilation. Casement replacement in those homes is a direct swap. Same opening, better seal, better airflow.

Bay Window Installation in Chicago
A bay window projects outward from the wall. That means more light, more interior floor space, and a stronger exterior profile — all from one installation. The standard configuration is three panels: a large fixed center unit flanked by two angled side units that can be operable or fixed depending on the need. Bow windows follow the same principle with a curved, multi-panel design suited to wider openings — available as an alternative where the wall allows it. Both styles change the character of the room they face. The difference is visible from the street and from inside. Greystone and two-flat buildings in Pilsen and Bridgeport often feature original bay window openings that are failing or were poorly replaced years ago. A proper bay window replacement restores the architectural detail, stops water infiltration at the projecting frame, and adds back the interior depth that the original design intended.
Picture Window Installation in Chicago
Some openings don't need ventilation. They need light and a clear view — nothing else. A picture window is fixed. It doesn't open. That means a simpler frame, a larger glass area, and a tighter seal than any operable unit. There are no moving parts to wear out. The entire opening is glass. Picture windows are often paired with operable units on the same wall — one fixed panel for light, one casement or double-hung for airflow. Fixed window installation covers the opening in one visit and requires no follow-up hardware adjustments. Homes in Evanston and along the North Shore with rear-facing views commonly use large picture windows to frame backyard and lakeside sightlines. The installation is straightforward — one day, no structural changes, and the visual impact is immediate from both inside and outside the home.
Custom Windows in Chicago
Not every opening takes a standard window. Non-standard sizes, arched tops, geometric shapes, and rough openings that have shifted over time all require units built to exact dimensions. Custom windows are ordered to precise field measurements — not trimmed down from a larger stock size. That distinction matters. A window cut to fit will never seal as well as one built to fit. Available styles include double-hung, casement, awning, picture, arched, and geometric configurations. Finish and hardware options are matched to the home's existing trim. The result is a clean installation with no filler strips, no visible gaps, and no compromised thermal performance. Historic greystone and coach house conversions in Wicker Park and Ukrainian Village frequently have rough openings that don't match any standard size. Made-to-measure windows are the only way to get a correct fit in those buildings without cutting into the masonry. We take field measurements on-site and order directly to those dimensions.
